Does diesel supply shock threaten farm profitability during harvest season?
Core argument: U.S. diesel prices hit a record $6.06/gallon, surpassing the prior peak of $5.82 set after Russia’s 2022 Ukraine invasion, as an Iran-driven supply shock tightens global fuel markets.
The diesel pump price has surged this year and rose to $6.06 on Friday, motorist group AAA said, above the previous record high of $5.82 in 2022 following Russia’s full-scale invasion of Ukraine. Diesel’s critical role in the transport supply chain is also feeding into surging producer prices, which can stoke inflationary pressures at a time when Americans increasingly feel squeezed by affordability. The jump in diesel comes ahead of the autumn high season, where the fuel is used to power agricultural equipment to harvest and transport crops. Grain farmers in America’s Corn Belt have said they are facing a crisis with rising fuel and fertiliser prices eating into profits.
